Hey,
So i was today in a hardware shop, i got the following answer from a owner of the shop who is selling stuff for years.
"One fan produce less noise then 2 fans" is that really accurate ?
Two fans that work with around 1000 rpm = 2x 1000rpm = 2000 rpm overall.
One fan that work with 1400 rpm = 1400 rpm overall
When i look this sheet it really makes sense, but is it really true ?
The card i am considering buying are Gigabyte 1050ti single fan or G1 Gaming 1050ti.
Is that really true or am i getting it wrong ?
Thanks for the info,
Cheers,

A 1000 rpm fan will be very quiet.
1400 rpm while not noisy will be louder.

But, two 120mm fans running at 1000 rpm will be louder than a single 140mm fan running at 800 rpm and moving the same amount of air.

This applies to case fans.
In a graphics card, you are looking at smaller fans, 92mm or 100mm.
How high the fans spin will be a function of load and how high the overclock is.
Most current graphics cards will have apps that allow you to make the trade off of rpm vs. cooling power.

Then also is the issue of case design. If a case has sufficient intake air capability there is not issue.
But, in a more restricted case, a graphics card with a small 90mm blower fan can be more efficient because it removes the heat out the back of...

often it is the opposite. the single fan runs faster and thus creates more noise. generally also the cooling takes a hit as well with a couple degrees higher temps. there are a lot of reasons to go with single fans such as smaller cases and the blower style cards for the same reason. but fi you have the room then a dual fan solution will yield a bit quiter and cooler performance.

as for the 1050ti however, it is such a low power card anyway that this may not even hold true. they should both be nice and cool n quiet no matter if it is one fan or 2

If the fans are the same size, and run at the same rpm, then two will be noisier.
But, a larger fan can push the same amount of air at a lower rpm and will be quieter.

Actually, any fan on a graphics card will be appropriate to the card.
Fancy fans and coolers sell.
GTX1050ti is not a hot card, so noise should not be an issue.
If you buy a highly overclocked card, expect it to run hotter and consequently have more noise.

If i have two 100mm fans running at 1000 rpm and one 100m fan running at 1400 rpm, will the 2 fans will be louder or quieter ?
P.S.
Thanks for the website link.
